Advanced Age May Not Be an Absolute Contraindication for Radical Nephroureterectomy in Patients with Upper Tract Urothelial Carcinoma: A Single-Center Case Series and a Systematic Review with Meta-Analyses

Abstract

Objective: This study aims to investigate whether advanced age is an absolute contraindication for radical nephroureterectomy (RNU) in patients with upper tract urothelial carcinoma (UTUC) through a single-center case series and a systematic review with meta-analysis. Materials and methods: In the single-center case series, 588 UTUC patients who underwent RNU between May 2003 and June 2019 in West China Hospital were enrolled, and cancer-specific survival (CSS) was the primary outcome of interest. In the systematic review with meta-analysis, PubMed, Scopus, Embase, and Cochrane databases were systematically searched for related articles for further analysis. The endpoints for meta-analyses were overall survival (OS) and CSS. Results: The single-center case series included 57 (9.7%) octogenarians. The CSS of octogenarians after RNU was comparable to that of younger people. Advanced age (≥80) was not an independent risk factor for poor CSS (HR, 1.08; 95% CI, 0.48, 2.40). In a systematic review with meta-analysis, the cut-off value of advanced age is 70, and the results showed that advanced age was associated with inferior OS (pooled HR, 1.55; 95% CI, 1.29, 2.01) and CSS (pooled HR, 1.37; 95% CI, 1.08, 1.65). However, the subgroup analysis of countries found no positive correlation between advanced age and CSS (pooled HR, 1.33; 95% CI 0.92, 1.74) in Chinese. Conclusions: Advanced age may no longer be an absolute contraindication for RNU. RNU can be safely and effectively performed on UTUC patients of advanced age after a comprehensive presurgical evaluation.
